I like this passage from Ursula Le Guin, from her book No Time to Spare:
Is a yin utopia a contradiction in terms, since all the familiar utopias rely on control to make them work, and yin does not control? Yet it is a great power. How does it work?
I can only guess. My guess is that the kind of thinking we are, at last, beginning to do about how to change the goals of human domination and unlimited growth to those of human adaptability and long-term survival is a shift from yang to yin, and so involves acceptance of impermanence and imperfection, a patience with uncertainty and the makeshift, a friendship with water, darkness, and the earth.
